They heal any mob your fighting now. So if your in melee at low level be prepared to kill them as well. Although they just heal and don't aggro but they are a real nuisance.
Ever notice how when these little fellows attack you nearby decaying skeletons attack you also? This has happened to me numerous times and was wondering if it was just me.
These guys are very brave. The attack me whenever I sit down. Blue conned Frogloks will walk past me, but these little buggers don't let up. Makes me feel bad when I turn them into mush.
